Design of Lithium Battery Charger Test System Based on STM32

Chao Yang, Liang Jiang


Aiming at the phenomenon of hot or even explosion when using unqualified charger to charge lithium battery at present, a charger test system based on STM32 is proposed. This design makes full use of STM32's excellent control ability to monitor and control the charging process of the charger in real time, and then judge whether it conforms to the lithium battery charging requirements in "GB/T 18287-2000 general specification for lithium ion battery for cellular phone". The test system designed in this paper has the advantages of high accuracy, good reliability, fast test speed, convenient operation and easy large-scale production and promotion.
